Liquid tuples, or liquid grooves, is a way of writting rhythms created (as far as I know) by
WTF grooves, a youtube/instagram channel.
Roughly, it consist on experiments substracting or adding units from tuples, while keeping the lenght of the subunits of the tuples. One can have, for example:
- A four note septuplet.
- A five note triplet.
- Nested modified tuplets (here is a website for a midi implementation).
It gets weird quickly, but it sounds great when applied properly.
